| Since the beginning of human civilization many herbs have so far been used for the treatment and management of various ailments. Spreading of bacterial resistance against antibiotics is consider one of the common problems in the medical world, so one of the most important steps in microbiological researches is to find a new antimicrobial compound with minimal side effects. One of wild herbs was Acacia ehrenbergiana Hayne commonly known as Salam, which was used as animal grazing herb especially camels, sheep and goat. Due to that it seems that this plant may contain considerable antimicrobial capacity. So the aim of this study is to investigate the antimicrobial activity of Acacia ehrenbergiana Hayne aqueous extracts on some medically important animal pathogens and to determine some phytochemical compounds. Hot and cold aqueous extract of Acacia ehrenbergiana Hayne were evaluated for their antimicrobial activity against some medically important pathogens isolated from animals and poultry farms (Staphylococcus epidermis, Escherichia coli, Streptococcus pyogens, Pseudomonas aerogenes, Salmonella typhimurium, Enterococcus, Bacillus cereus, Klebsiella pneumoniae and Candida albicans) by agar well diffusion method. Both hot and cold aqueous extract showed high antibacterial effect against the all examined pathogenic bacteria samples. While the extracts did not show any significant antifungal activity against Candida albicans. Also, phytochemical compoud of aqueous extract was determined, results of the chemical tests explain the extracts of Acacia ehrenbergiana Hayne contain alkaloids, flavnoids, tannins and saponin compounds. So it could be concluded that the Acacia ehrenbergiana Hayne extract possess remarkable antibacterial activity against gram positive and gram negative bacteria and to be introduced as an alternative to chemical antimicrobial drugs, is required wider investigation.

“…Phytochemical constituents such as tannins, saponins, flavonoids, alkaloids, and several other aromatic compounds are secondary metabolites of plants that serve as defense mechanisms against predation by many microorganisms, insects, and other herbivores. (Rehab, 2017;Chung et al, 1993).…”

“…Besides, Chung et al [12] reported that tannic acid inhibited the growth of all selected food-borne bacteria while gallic and ellagic acid could not inhibit any of them. Chung et al [12] and [13] reported that the ester linkage between gallic acid and glucose (to form tannic acid) was important for the antimicrobial potential of these compounds.…”

Eco-friendly leather processes based on the usage of natural products have become a potentially attractive issue for leather industry during the last few decades. Synthetic protective chemicals like bactericides used in most soaking process are known as hazardous substances and cause tannery effl uents with high concentrations of Chemical Oxygen Demand (COD). In the present study, the effect of tannic acid on microorganisms, skin, wool and effl uent were investigated in order to demonstrate the applicability of tannic acid in soaking process instead of commonly used bactericides. The bacterial load (cfu/ml), COD and Nitrogen Content (N) of the soaking effl uents and Total Kjeldahl Nitrogen (TKN) content of skins and wools were investigated. Application of 0.5 and 1 wt% tannic acid concentrations was more effective than commercial bactericide, while comparable results were achieved by 0.1 and 0.3 wt% tannic acid. The application of tannic acid for soaking process resulted in lower COD and N values of effl uents. The results show that tannic acid has the potential to be an alternative, eco-friendly bactericide for leather industry by reducing the pollution of leather soaking process.

“…Terpenoids and flavonoids act as an effective antimicrobial agent due to its ability to disrupt the membrane of lipophilic compounds present in the microbial cell [52]. The antibacterial ability of the extract may also be due to the ability of tannin to hydrolyze the ester linkage between gallic acid and polyols [53]. Thus, tannin-rich plant parts have natural defense against microbial infection [54].…”

Objective: The current study was aimed to investigate the potential phytoconstituents from Casuarina equisetifolia root extract. Qualitative, quantitative and gas chromatography-mass spectrometry (GC-MS) analysis of C. equisetifolia using various solvents of root extract was also carried out to characterize the presence of various bioactive compounds in the root. The research work was also targeted to reveal the antibacterial, antioxidant, and anti-inflammatory potential of the root extract of C. equisetifolia. Methods:Root samples of C. equisetifolia were collected from Nimilenchery village, Pondicherry Union territory. The qualitative screening of the root extracts was carried out to check the presence of various phytoconstituents which was then followed by the quantitative analysis of phenols, flavonoids, and tannins. Further, the phytochemicals in the root extract were evaluated using GC-MS studies. In vitro antibacterial activity was performed by the agar well diffusion method using aqueous and organic solvent-based root extract against four different bacterial pathogens. In vitro antioxidant assay of different solvent extracts was elucidated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, hydrogen peroxide radical scavenging assay, and reducing power assay. Anti-inflammatory potential was also studied using protein denaturation of albumin. Results:The qualitative phytochemical screening revealed the presence of various phytoconstituents which is of greater biological importance. Gallic acid equivalent (GAE) phenolic compound content (68.64±0.25 mg GAE/g of extract), quercetin equivalent flavonoid content (29.09±0.14 mg of QUE/g of extract), tannic acid equivalent (TAE) tannin content (51±0.42 mg TAE/g of extract), and terpenoid content (5.2%) were found to be significant in the methanol root extract of C. equisetifolia when compared with other solvents. GC-MS analysis revealed different peaks indicating the presence of different secondary metabolites. Prominent antibacterial activity was observed in methanol extract of root, with maximum zone of inhibition exhibited against Proteus vulgaris (23.45±0.28 mm). The methanol root extract was most effective with half maximal inhibitory concentration (IC 50 ) 52.74±0.65 µg/ml for DPPH and 64.94±0.24 μg/ml for hydrogen peroxide scavenging activity. Maximum absorbance was observed by 80 µg/ml (IC 50 51.79±0.26 µg/ml) of methanol root extract with respect to reducing power assay. In vitro anti-inflammatory activity had maximum inhibition of 84.6±0.26 with IC 50 value of 33.6±0.23 μg/ml at 80 μg/ml. Conclusion:From this study, it is revealed that the species of C. equisetifolia is a source of potential phytoconstituents exhibiting significantly various biological activities leading to the development of novel drug.
